Filed: 1988-11-11
Abstract: PURPOSE:To eliminate the generation of powdery dust by wear and to prevent the reliability of the title device from lowering by ejecting a disk after stopping the rotation of a turntable upon detecting the operation of an eject button. CONSTITUTION:When an eject button is pressed, the ejecting operation detecting switch 217 of a drive device 2 is turned on and the ejecting operation is detected. Then a system controlling section 212 discriminates whether or not recording/reproducing operations are executed through a recording and reproducing section 206. When the discriminated result is 'no' and loading lock is released, a stop signal is supplied to a spindle motor controlling section from the section 212 and rotation of a turntable 21 is stopped. Simultaneously, a moving mechanism which is released from loading locked state by means of magnets 22, etc., is moved when the eject button is pressed and an optical disk 11 is ejected after the chucking between the turntable 21 and an optical disk 11 is released. Therefore, generation of powdery dust by the friction between the lifting section 13 of a cartridge 1 and the disk 11 is eliminated and a decline in reliability of this cartridge type disk storage device can be prevented.

Filed: 1986-12-01
Abstract: PURPOSE:To enable a uniform etching by having a specific pattern for obtaining a uniform etch rate at the etching time, thereby eliminating a difference in the etch rate due to the pattern density. CONSTITUTION:A circuit pattern 22 is formed on a semiconductor substrate by the use of an etching using an etchant-resistant resist.

Filed: 1995-11-01
Abstract: PROBLEM TO BE SOLVED: To provide a II-VI compound semiconductor laser, in which the increase in resistance of a current constriction layer in a mesa structure is prevented and the heat generation due to current concentration is reduced. SOLUTION: A semiconductor device comprises an n-GaAs substrate 11, on which a clad layer 12 of n-ZnMgSSe, an optical waveguide layer 13 of n- ZnSSe, a SQW active layer 14, an optical waveguide layer 15 of p-ZnSSe, a clad layer 18 of p-ZnMgSSe, a superlattice contact layer 19 of ZnTe/ZnSe and a cap layer 20 of p-ZnTe are formed.

IPC: B60K17/344
Filed: 1986-11-28
Abstract: PURPOSE:To cut off the restraint of rotation of front and rear wheels so as to prevent a lock of rear wheels at the time of brake operation of a vehicle by providing a control device restricting the output current of a motor to nearly zero when the rotation of rear wheels is going to exceed the rotation of front wheels. CONSTITUTION:A motor 11 is constituted of a rotor 12, a stator 13, and a resistor 15, and the stator 13 is connected to the driving device 1 side. A diode 16 is connected in series with the resistor 15 to constitute a control device 21. When the rotation of rear wheels is going to exceed the rotation of front wheels 4, the diode 16 cuts off the reverse current generated in the motor 11. At the time of brake operation, the rotation of rear wheels is going to exceed the rotation of front wheels by the brake force distribution and feed the reverse current when front wheels are locked, but this current is cut off by the diode 16 to prevent the power generation braking by the motor 11. Accordingly, the rotation restraint of front wheels and rear wheels is cut off, and a lock of rear wheels is prevented.
